Well, it depends on the fund. If your parish takes a collection for a mission run by nuns to help feed and educate an African village, you can bet those nuns aren't spending that money on anything but the African village. If the money is going to the Archdiocese, you run into "administrative costs". Although the Catholic Standard and Times published the ADP's annual budget for the past year down to the dollar with where the money goes and I don't remember reading anything out of the ordinary (you had education, aid, etc). I'm no fan of the AD because too often it comes off sounding more like a business than a source of Christ (that doesn't apply to individual parishes or missions). But I can only criticize based on what I know.
